INPAK SYSTEMS offers a wide selection of valve bag filling machines. Because material is filled through a “valve” in the bag rather than poured into an open mouth, valve bag fillers are ideal when cleanliness and efficiency are a necessity. Also, valve bags do not require bag sewing or bag sealing equipment to close the bag. See our post Types of Valve Bags for more information.
Valve bag fillers are available with gravity, impeller, auger, air packer, or compaction feeder. The characteristics of the material and environment dictate the type of valve bagger utilized. Valve bagging scales are capable of filling 20-220 lbs. Valve type bags at a rate of 1-12 bags/minute.

Air Packer Valve Baggers
Sometimes called Forced Flow or Pneumatic Packers, Air Packers are used for free flowing, low humidity, dry flakes, powders & small size granules that cannot be heated, ground or crushed. Applications include: Portland cement, sugar, calcium carbonate, PVC pellets and lime.Auger Valve Baggers
Sometimes called Screw Baggers, Auger Baggers are designed for flakes, powders, pellets, granules, and fibrous material that may be heated, ground or crushed. Applications include: abrasives, cellulose, fiber, compost, flour, grain, insulation, limestone, minerals, moss, mulch, pepper, pigment, plastic pellets, resins, rubber, salt, sand, sawdust, soils & sugar.Compaction Valve Baggers
Compaction baggers are designed to fill valve type bags by volume rather than weight. Typical products include fibrous or compressible materials such as soils, sawdust, and cellulose fiber.Gravity Valve Baggers
Gravity baggers are used for free flowing, high density materials like flakes, granules or pellets where the product easily falls into a hopper. Applications include corn, grains, fertilizer, refractory materials, plastic pellets, salt, sand, soybean and sugar.Impeller Valve Baggers
Sometimes called a turbine packers, Impeller Baggers are ideal for fine, dry, high bulk density (>50#/cuft.) powders of less than 200 mesh where crushing or fines are not an issue. Applications are fly ash, carbon black, cement, kaolin, clay, graphite, polystyrene, silica and vermiculite.Valve Type Bag Fillers FAQs
The primary difference lies in the sealing mechanism and dust control. Open-mouth systems require secondary sewing or heat sealing system. With valve bag filling systems, the bag self-seals reducing airborne dust.
Valve bag fillers are optimized for dense, fine powders, granular materials, and flaked products. This includes industrial chemicals, cement mixes, flour, pigments, and agricultural minerals.
- Impeller fillers are best for dense, fine minerals like hydrated lime or graphite.
- Pneumatic (air packer, air stone) fillers are ideal for abrasive materials or blended mixes (like dry concrete mixes)
- Auger fillers are best for consistent volumetric dosing of cohesive powders, bakery mixes, or sticky starches.
Contact our technical engineers with your products and the can recommend a model that meets your needs.
Standard commercial valve bag fillers support a weight range of 20 lbs. to 110 lbs. (10 kg to 50 kg).
Throughput depends on the degree of automation and material properties. A single-spout, operator-fed pneumatic valve bagger averages 3 to 5 BPM. An automatic bag placer increases single-spout output to 8 to 10 BPM. A multi-spout carousel configuration achieve speeds exceeding 24 to 30 BPM.
Yes, to achieve total dust-free operation, valve baggers should be connected to a facility dust collector.
Ultrasonic sealing modules create a hermetic, sift-proof seal that prevents moisture ingress, contamination, and product leakage. Recommended for hygroscopic chemicals and food products to maximize shelf stability.
Yes, upgrades are available. Contact our technical engineers with your material to be bagged and they can recommend a model that meets your requirements.
Yes, installation, training, and/or service contracts are available,
The warranty period is established by the manufacturer and is typically 12 mos.
